Hereinafter, the determination procedure executed by the processing unit 16 in step S1 will be described in detail with reference to FIG. 4. The determination procedure includes, for example, the following steps S11 to S17. First, the processing unit 16 first determines whether the external temperature of the environment in which the refrigerator 2 is located is within the predetermined temperature range according to the external temperature data T ₁ (step S11). If the determination result is positive, the flow proceeds to step S12, Otherwise, the flow proceeds to S3. Next, the processing unit 16 determines whether the brightness of the environment in which the refrigerator 2 is located is within the predetermined brightness range according to the brightness data B (step S12). If the determination result is positive, the flow proceeds to step S13, otherwise the flow proceeds to S3 . Then, the processing unit 16 determines whether the temperature of the first storage space portion 211a of the internal storage space 211 is lower than the predetermined first threshold temperature according to the first temperature data T ₂ (step S13), and if the determination result is positive At this time, the flow proceeds to step S14, otherwise the flow proceeds to S3. After that, the processing unit 16 determines whether the temperature of the second storage space portion 211b of the internal storage space 211 is lower than the predetermined second threshold temperature according to the second temperature data T ₃ (step S14), and if the determination result is positive At this time, the flow proceeds to step S15, otherwise the flow proceeds to S3. After that, the processing unit 16 determines whether the historical cumulative opening / closing times is less than the predetermined threshold number according to the frequency data N (step S15). If the determination result is positive, the flow proceeds to step S16, otherwise the flow proceeds to S3. After that, the processing unit 16 determines whether the current rotation speed of the compressor 22 is less than the predetermined threshold rotation speed according to the rotation speed data R (step S16). If the determination result is positive, the flow proceeds to step S17, otherwise the flow proceeds to S3. Finally, the processing unit 16 determines whether the historical cumulative operating time of the compressor 22 is shorter than the predetermined first threshold time according to the second time data t ₂ (step S17). If the determination result is positive, the flow proceeds to step S2, otherwise the flow proceeds to S3. It is worth noting that the order of steps S11-S17 is not limited to this embodiment, and in other embodiments, the order of steps S11-S17 can be arbitrarily changed.

In step S2, the processing unit 16 selects the first operation mode as the target mode, and controls the refrigerator 2 to operate in the target mode.

In step S3, the processing unit 16 determines not only the environmental data but also the weather information I indicating the weather conditions of the geographical area where the refrigerator 2 is located, to determine whether the weather conditions and the humidity of the environment where the refrigerator 2 is located completely meet A second reference condition corresponding to the second operation mode. If the determination result is positive, the flow proceeds to step S4, otherwise the flow proceeds to step S5.

In this embodiment, the second reference condition includes, for example, a predetermined rain condition and a predetermined threshold humidity. For example, the predetermined threshold humidity may be 65% RH, but is not limited thereto.

Hereinafter, the determination program executed by the processing unit 16 in step S3 will be described in detail with reference to FIG. 5. The determination program includes, for example, the following steps S31 to S34. First, the processing unit 16 determines whether the weather condition indicated by the weather information I is the predetermined rain condition (step S31). If the determination result is positive, the flow proceeds to step S32, otherwise the flow proceeds to S5. When the processing unit 16 determines that the weather condition is the rain condition, in step S32, the processing unit 16 generates and outputs the enable signal to the humidity sensing module 112, so that the humidity sensing module 112 is in When receiving the enable signal from the processing unit 16, it is activated to sense the humidity of the environment in which the refrigerator 2 is located and generate and output the humidity data H to the processing unit 16. After that, the processing unit 16 receives the humidity data H from the humidity sensing module 112 (step S33). Next, in step S34, the processing unit 16 determines whether the humidity of the environment where the refrigerator 2 is located is less than the predetermined threshold humidity according to the humidity data. If the determination result is positive, the flow proceeds to step S4, otherwise, the flow proceeds to step S5.

It is worth noting that, in this embodiment, the humidity sensing module 112 is activated by the processing unit 16 only when the processing unit 16 determines that the weather condition indicated by the weather information I is a rain condition, so It can relatively save the power consumed by the energy-saving control system 1, that is, save the overall power consumption of the refrigerator 2.

In step S4, the processing unit 16 selects the second operation mode as the target mode, and controls the refrigerator 2 to operate in the target mode.

In step S5, the processing unit 16 t ₁ based on the first time information, it is determined that the accumulated on-time history meets a condition corresponding to the third reference to the third mode of operation. If the determination result is positive, the flow proceeds to step S6, otherwise the flow proceeds to step S7. In this embodiment, the third reference condition includes, for example, a predetermined second threshold time. For example, the predetermined second threshold time may be 3 hours, but is not limited thereto. More specifically, the processing unit 16 executes the determination of whether the historical cumulative opening time meets the third reference condition by determining whether the historical cumulative opening time is shorter than the predetermined second threshold time.

In step S6, the processing unit 16 selects the third operation mode as the target mode, and controls the refrigerator 2 to operate in the target mode.

In step S7, the processing unit 16 selects the fourth operation mode as the target mode, and controls the refrigerator 2 to operate in the target mode.

In summary, in this embodiment, since the processing unit 16 is based on the external temperature data T ₁ , the humidity data H, the brightness data B, the first temperature data T ₂ , and the second temperature data T ₃ , The frequency data N, the first time data t ₁ , the rotation speed data R, the weather information I, and the second time data t ₂ , one of the first to fourth operation modes is selected as a target mode And control the refrigerator 2 to operate in the target mode. Therefore, the refrigerator 2 can be operated at the target in an adaptive manner to the current external environment, the current temperature condition of the internal storage space 211, the opening and closing state of the first tank door 212, and the operation condition of the compressor 22. The mode is not only beneficial for keeping cold and freshness of the food stored therein, but also for the refrigerator 2 to utilize energy in a relatively efficient manner. In addition, since the humidity sensing module 112 is in an inactive state before receiving the enabling signal, the power consumed by the energy-saving control system 1 can be relatively saved. Therefore, it can indeed achieve the purpose of the invention.

However, the above are only examples of the present invention. When the scope of implementation of the present invention cannot be limited in this way, any simple equivalent changes and modifications made in accordance with the scope of the patent application and the content of the patent specification of the present invention are still Within the scope of the invention patent.
